Interior rear panel ideas

[Galair]

Does anyone have any ideas for non carpeted rear panels, I have put rgm wheel arch and pillar covers on,and want something that will wipe down easy buy not bare plywood or the basic vw ones.
I've also put the plastic inserts in the sliders from kiravans.
But struggling to think what to do the the back bit?

I’m thinking to replace my Kombi panels with something like this once I’ve had my leaky sliding windows replaced.
